Applications
An Ethernet to Fiber Media Converter can also be used where there is high level of electromagnetic interference or EMI which is a common phenomenon found in industrial plants. This interference can cause corruption of data over copper-based ethernet links. Data transmitted over fiber optic cable however is completely immune to this type of noise. An Ethernet to Fiber Optic Converter therefore enables you to inter-connect your copper-ethernet devices over fiber ensuring optimal data transmission across the plant floor.

RS232 Modem and RS422 Modem Difference
All serial converters feature a minimum of an Ethernet port and software-selectable RS232/422/485 serial interfaces, and meet IEC safety (IEC 60950-1) and EMC (EN 61000) standards. They support various protocols for serial data transmission including Modbus/TCP, raw serial data over UTP, IPv4 and IPv6.
The 4 and 8 port RS422/485 devices, as with the rest of the range, will enable connection across a network with no loss of reliability or signal integrity. The Port3 connector signal level is of RS485 or RS232. This port can be stated as a general CPU module communication port and utilized for peripheral applications.
One of the major differences between RS232 Modem and RS422/RS485 is the signaling mode. RS232 is unbalanced while RS422/RS485 is balanced. An unbalanced signal is represented by a single signal wire where a voltage level on that one wire is used to transmit/receive binary 1 and 0: it can be considered a push signal driver. On the other hand, a balanced signal is represented by a pair of wires where a voltage difference is used to transmit/receive binary information: sort of a push-pull signal driver. In short, unbalanced voltage level signal travels slower and shorter than a balanced voltage difference signal.
